Abstract: A display device and a backlight control method of the display device are provided. When a duration of an image occlusion period is shorter than a preset duration, a backlight driving circuit is controlled to respectively provide a first pulse current and a second pulse current in a first light emitting period and a second light emitting period in each frame period, so as to drive a backlight unit to provide a first backlight and a second backlight. Here, the first pulse current is greater than the second pulse current.

Abstract: A method of controlling a display device includes obtaining a duty cycle of a backlight control signal, and adjusting a starting time of a pulse in the backlight control signal at least according to the duty cycle. The backlight control signal is used to control a backlight of the display device.

Abstract: A method includes sorting a plurality of scanning time lengths of the plurality of transmission ports in an ascending order, generating a scanning priority table after the plurality of scanning time lengths of the plurality of transmission ports are sorted, and scanning at least two transmission ports according to the scanning priority table. A transmission port with a higher priority has a shorter scanning time length. A transmission port with a lower priority has a longer scanning time length.

Abstract: A display device includes a casing, a display unit, an optical sensing unit, a driving unit and a processing unit. The processing unit controls the display unit to display a predetermined pattern corresponding to a predetermined range. The predetermined pattern includes a target area. The target area is adjacent to a target position and corresponds to a driving parameter of the driving unit. When the optical sensing unit is located within the target area, the driving unit drives the optical sensing unit to move to the target position by a predetermined manner. When the optical sensing unit is located beyond the target area, the driving unit drives the optical sensing unit to move towards the target position. When the optical sensing unit moves to a boundary of the target area, the driving unit drives the optical sensing unit to move to the target position by the driving parameter.
